WASHINGTON (AP) — Joe Biden’s presidential campaign said Thursday that vice presidential nominee Kamala Harris will suspend in-person events until Monday after two people associated with the campaign tested positive for coronavirus.

The campaign said Biden had no exposure, though he and Harris spent several hours campaigning together in Arizona on Oct. 8.

“After being with Senator Harris, both individuals attended personal, non-campaign events in the past week. Under our campaign’s strict health protocols, both individuals had to be tested before returning to their work with the campaign from these personal events.  These protocols help protect the campaign, the staff, and anyone who they may have contact with; the importance of having such protocols — which include testing before resuming duties, regular testing while working in-person, isolation after time off, and masking and distancing while on campaign duties — have been illustrated once again.”

Harris was scheduled to travel Thursday to North Carolina for events encouraging voters to cast early ballots.

The campaign told reporters Thursday morning that Harris’ communications director and a traveling staff member for her travel to Arizona tested positive after that Oct. 8 trip.

Harris and Biden spent several hours together that day through multiple campaign stops, private meetings and a joint appearance in front of reporters at an airport. They were masked at all times in public, and aides said they were masked in private, as well. Biden and Harris have each had multiple negative tests since then.

“The campaign has begun the contact tracing process to notify everyone who came into contact with the individuals during the potential infection window,” Biden campaign manager Jen O’Malley Dillon said in the statement. “The laboratory which conducts tests on our behalf has reported these results, as they do all of our test results, to local officials as required by law.”

Biden is scheduled to attend an ABC News town hall airing live at 8 p.m. EDT.
